Essential to remember is that the pattern of referred pain in no way hints at the spinal level involved. Multiple studies confirm that there is considerable overlap in the distribution of pain stemming from the zygapophyseal joints, including anterior, lateral or posterior thigh, groin, lumbar spine region, and trochanter region.
Referred pain, also called reflective pain, [1] is pain perceived at a location other than the site of the painful stimulus.An example is the case of angina pectoris brought on by a myocardial infarction (heart attack), where pain is often felt in the left side of neck, left shoulder, and back rather than in the thorax (chest), the site of the injury.
Typically, the pain is worsened by stress on the facet joints, e.g. by lumbar extension and loading (the basis of the Kemp test) or lateral flexion but also by prolonged standing or walking. [citation needed] Pain associated with facet syndrome is often called "referred pain" because symptoms do not follow a specific nerve root pattern. This is ...
The lower subscapular nerve contains axons from the ventral rami of the C5 and C6 cervical spinal nerves. [2] [3] It is the third branch of the posterior cord of the brachial plexus.
The fourth lumbar spinal nerve (L4) [4] originates from the spinal column from below the lumbar vertebra 4 (L4). L4 supplies many muscles, either directly or through nerves originating from L4. They are not innervated with L4 as single origin, but partly by L4 and partly by other spinal nerves. The muscles are: quadratus lumborum; gluteus ...
Snapping (grating) scapula . Snapping scapula syndrome, also known as scapulocostal syndrome or scapulothoracic syndrome, is described by a "grating, grinding, popping or snapping sensation of the scapula onto the back side of the ribs or thoracic area of the spine" (Hauser).
The lower subscapular nerve contains two branches. One branch inserts into the lower portion of the subscapularis muscle and the other branch inserts into the teres major. In some individuals, accessory upper subscapular nerve or accessory lower subscapular nerve may be found. [2]
